Is it just me or everyone else that is experiencing a super long time in charging their phone to full battery? I am running the froyostone latest build and I have already followed all the guides in this forum to save battery life. The issue I am having is that it takes many hours to recharge the battery to full when connected to a wall charger.
It took 5 hours to go from 30% battery to 90%.

I have a stock battery, which I can charge from 25% or less to 100% in about 30 minutes to an hour. I think there is something wrong with your charger.
its actually not taking that long, it probably got to 90% VERY quickly, you just checked on it later... they're false numbers... what you need to do is this; run your battery all the way down.. then charge it for about 1-2hrs, until it gets somewhere in the 90's then, while plugged in, shut the phone down, remove the battery, put the battery back in, boot up the phone (the phone should remain plugged in) then load up WM, load up android with the hard buttons backlight on, then once it boots you should show higher than what you had before (if not 100%) from this point android will remember your charge and you will be able to go to 100% all the time now. (until you load a new rom)

What kernel are you using?

I am using hastarin r8 kernel, but I was experiencing the same issue with previous versions and the default kernel.
I just tested the charging rate by connecting my HD2 to a stock charger from HTC which I borrowed from a friend. Charging was a lot faster.
Since I bought my HD2 used, the charger that came with it, is not the stock charger from HTC.
But I still don't understand what is causing the charging to be very slow.
How to calculate charging time
Charging time = capacity of battery x 1,4 / charging current
HD2 stock battery= 1230mAh x 1,4 / 1000mA = 1,7 hours

Two things on charging batteries:
1) First, make sure none of the pins in the battery compartment is bent. This dramatically slowed charging for me once.
2) Android keeps battery stats in a file that gets loaded with your build. THese stats are often wrong. Be sure to fully charge under WinMo, then with power still attached, boot into Android. This will adjust some of the stats and charging in Android should be fine then. There's a thread somewhere on more details here if you want to tweak your stats. The battery slows down its charging when it gets close to the full state. If for some reason your charger thinks the temperature is getting too high or the state is getting near full it dramatically slows the charging rate. Both of these could be erroneous interpretations of the battery data. Also, if you have an extended battery, make sure to use a Kernel that is compatible with extended batteries, like Hastarin 7.x.

Not all chargers are built the same. Some usb charger provide more juice while others provide less. Maybe your non stock charger came from a non smart phone...

Current Widget from the Market can tell you how many mA your phone is getting when it's charging.
this is just an approximation formula. a lithium ion battery charger is more sophisticated than this. it first brings battery voltage up to 20% safely (because any voltage below this is the harmful zone of operation), then it stuffs the battery at full capacity upto 80%. then in the 3rd stage, the current drops linearly with time.
over the past year, my stock battery gives me the following profile:
20-80% -> 1 hour (800-820ma constant, unless phone is awake)
80-100% -> 1 hour (800 -> 0ma)
by 100% i mean 0ma charge current. not 100% on the battery icon. you should be aware that the battery is still charging even after the indicator reaches 100%. but the current is insignificant (10-20ma)
even though the charger is rated at 5v 1A, it supplies only 820ma current at the maximum. this is normal. also for a lion battery the safe operating regions are around 20-90%. by safe i mean prolonging battery life. this roughly corresponds to 3.6v - 4.0v. avoid overcharging your battery frequently.
also someone mentioned current widget as a good approximate tool to study battery performance. you might also want to delete batterystats.bin and condition your battery once (i.e. fully discharge and fully recharge). this will force android to re-determine the new 0% and 100% levels. search the android forums for this.
hope this helps.

wow ! thanks alot !
Is it bad to let my charge over night overnight? I thought it would stop charging when it got full to avoid overhanging.

Since I have access to a a battery simulator and charger... the best way to recondition a battery is:
1. Create a low battery scenario by lowering the input voltage to just a hair above 2.7 volts (I had to create a shim to get to the battery receiver leads).
2. Boot with full 4.2 and in ClockWork remove battery stats
3. Drain and Charge battery to 4.2
I get enterprise email and I get a lot of mail daily that I have to read and respond to (150 or more -- no I don't respond to all of them), plus the phone calls, RSS reading and some texting plus a pic here and there and maybe a couple of you tube videos. I get more than 24 hours until the 15 % comes up. 50 hours would be nice but that did not even happen in my black berry with Edge only.
Mine improve 3 fold from sub 7 hours to 24 plus (yes I sleep late so probably the phone gets a 6 hour rest but the enterprise email and text is pushed down even then as I work with folks from Asia and Europe as well.

Yes, the "charger" that you plug into the wall is just a power supply, the actual "charger" is in the phone, and when it detects the battery is full it stops charging.
HI, I'm going to receive my phone this afternoon..just confirmed by DHL Malaysia.
can I know how many hours you guys charged your SGS2 for first time battery charge.
Is it necessary to charge 8 hours for first time use?
Please share your experiences
for my past phone , nexus 1 and nexus s, I charged 8 hours for first time use and 8 hours for my extended batteries as well..
from my understanding, you don't need a extra long first charge for Li-ion batteries, you only need to prevent overcharge/overdischarge which is taken care of by the battery protection circuits.
In other words, turn on and start using it like normal
Just plug it in, charge it. When it's full unplug it.
Took me 1h to charge it up from half. Battery came with half charge.
Thanks mates, I'm charging the phone now
until it's full, I will unplug..
Try to run it through a few full cycles when you first get it though...
do u mean it has to be drain out before next charging?
I think it's a good idea to go from 0 to 100 in the beginning. Not for the battery sake more for the phone to learn what max and min are.
I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?

Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.
Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.

Okay I googled this and I have gotten mixed results some saying that lithium ion batteries doesn't need to be charged for hours while others are actually saying it's still needed or let it drain to 20 % charge to 100% then drain to 20% then charge to 80% i did Google lithium ion batteries it did say they don't need to be charged for hours but every device I have brand new or not including my brand new iPod 6 I have now don't ask I'm leaving iOS actually lol all have poor battery life so I need to stop blaming the manufacturers and start blaming myself lol please any help would be appreciated

For the 1st Time or after You Flashed any ROM/Firmware You Should Complete 3 Complete Cycles of Battery To Get The Best Results...
Charge 100% To Discharge 5% (Do Complete 3 Cycles )
Regarding Charging You will Not be need to Put Note 4 All Night Charging or Stuff like More Charging Then 1:30hours,Because it Have Adaptive Fast Charging Battery Will Charge in 1:30Hours & Give you 5:30hours SOT (it Depends on your usage also)...
Now Mostly Smartphones Have Built-in Feature To Stop Charging When It's Fully Charged...So No Need To Worry...But Every Battery Have Some Cycles when You reach that then battery will drain Fast or we can say You'll be in Condition to replace the Battery...But Will Easily Last for 2 or 3 Years To be Weak on...
Hope will Solve your issue
Okay thanks so much so basically I'll charge it to 100% without using it I'm guessing it's a quick charge so it wouldn't be an issue for me then use it to 5% 3 times sorry I'm a.d.d. So had to make sure I read what you said correctly and I'm not sure if I'm gonna root it when I get it phones no days are actually beginning to meet my standards speed wise lol thanks for the info
I've found no noticeable difference in following different guides on charging. Turn off fast charging when not required as that'll duff up your battery in 6 months.. Normal charging provides a nice slow rate and ensures they don't get hot which degrades them. A new battery will take a few full charges to get to full strength.
A new battery is like £!2. Don't worry about doing rain dances and such like!
Batteries used to hold a memory effect which made it look full before it actually was - this isn't the case anymore.
Fast charging gives me an hour less per day over constant charging normally. Note sure what others have found. I charge overnight hence turning off fast charge, and have a couple of spares ready to go should I need it.
i charge 14 hours and then use it normally. no need for anything more than that.
This is puzzling. I got the Samsung Galaxy S8+ ZeroLemon 8500 mAh battery. Verizon FWIW. I plugged the phone in it and charged the phone via the extended battery port. The phone charged to 100% overnight (I kept on the charger for 7 hours).
When I removed the phone off the charger, I ran it to 1% in 11 hours. I was under the impression that I should have gotten much better runtime than that, based on my experience with multiple ZeroLemon devices. At least 24 hours. And that 11 hours did not get a lot of screen time.
When I removed the phone from the ZeroLemon 8500 cell, it did not appear to have been used, all of the 4 lights still light up, indicating it is full. I was not sure how to pull the voltage off of it. But if it got drained, none of the lights would light up, correct? If it's full after a day of usage, the phone shuts down getting drained to 3500 mAh or so without accessing the external ZeroLemon battery, why? Where is the disconnect? Could it be somehow it did not get fully charged over 7 hours? If so, why are the lights on?
could it be that the 8500 mAh cell only got charged half-way or a third of the way there, which makes the 11 hour figure plausible. I know the phone cannot get 11 hours off the stock 3500mAh cell, it's lucky to get 6 to 8 hours.. 3500 mAh is completely inadequate for a 2960x1440 resolution device so the increased resolution drains it that much faster.
The external ZeroLemon battery has to be turned on. Unlike many internal ZL batteries I've had over the years. I assumed it was the same thing. You have to push the button.
